Kaydon Reali-Slim® sealed bearings

JU series (double sealed)
Type C – radial contact

A Conrad assembled bearing designed primarily for application of radial load—deep ball grooves also permit application of some thrust load in either direction—often used in conjunction with another bearing.

Notes
1 Capacities listed are not simultaneous. For combined loading see discussion of Bearing Selection and Load Analysis in the Kaydon Reali-Slim® bearing catalog. Dynamic capacities are based upon 1 million revolutions of L10 life. Published capacities do not apply to hybrid series bearings P, X, and Y. Contact Kaydon product engineering for values.
2 Static capacities are non-brinell limits based on rigid support from the shaft and housing.
3 ISO Radial ratings are calculated per ISO 281:1990. They are included for comparison only.
4 Torque figures shown are for single bearings with standard lubricant at room temperature and under 5 pounds thrust load.
5 "F" is the maximum shaft or housing fillet radius the bearing corners will clear.
* Values apply to bearings loaded up to 20% of their dynamic capacity.
 
Sealed series bearings are supplied with general purpose grease, satisfactory for operating temperatures of -40°F to +250°F (-40°C to +121°C). Other lubricants are available on special order.
